Murwillumbah sits low in the Tweed Valley beneath Mount Warning, a setting that traps humidity and can hold smoke and haze close to the ground on calm days, more so than exposed coastal towns nearby. Sugarcane burning on the surrounding Tweed lowlands historically added smoke during the cooler months, alongside bushfire smoke from forested hinterland in drier spells. Wet season humidity is a defining feature. The valley's vegetation and low traffic volumes otherwise keep background air quality generally good.

Is air quality bad in Murwillumbah right now?
On 4 August 2026, overall air quality in Murwillumbah is poor. AQI is the main air quality indicator at 66.0/100. Pollution peaks around 11:00 PM (NO2: 66.0/100).

On 5 August 2026, air quality conditions in Murwillumbah will be similar to today, with AQI forecast at poor at 65.9/100. Pollution peaks around 9:00 PM (NO2: 65.9/100).
When is air pollution at its worst in Murwillumbah?
Sitting low in the Tweed Valley, Murwillumbah is particularly prone to smoke pooling overnight during cane-burning season (roughly June to December) and pre-wet-season hazard-reduction burns (August–November), with haze often lingering until the morning breeze arrives. Outside these windows the valley's air is generally clean, so plan outdoor activity around clearer afternoons in burn season.
Are air quality levels in Murwillumbah based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
